| Abstract | ||
| To monitor a multivariate process classical Hotelling's T2 control chart is often used. However , it is well known that such control charts are very sensitive to the presence of outlying observations in the historical phase I data used to set up its control limits . In this paper we used arobust Hotelling's T2 type control chart for individual observations based on robust and efficient estimators of location and scatter known as re_weighted minimum covariance determinant (RMCD) estimators . | ||
